Send a MODE request when JOINing
This kind of reverts/fixes f1cb09bd9ce0489d96f4ef91b3e226e0b0a37662.
Robby found a bug with evil ChanServ which goes like this:
- You join an empty, but registered channel and the IRCd applies its default
modes (+nt), but ZNC didn't ask for MODE, so doesn't know this.
- ChanServ applies whatever channel modes it wants to apply. This causes ZNC to
see a mode change (e.g. +s).
The result of this is that ZNC thinks that the channel has mode +s and it will
tell every client that connects to it about this.
The fix is to send a MODE request when JOINing. To make sure that we don't
confuse clients, we block the reply.
